INFORMATIONAL-MEASURING RADIO SYSTEM Russian patent published in 2006 - IPC H04B1/69 H04B7/216 

FIELD: method and device for transferring information by M-based system of symbols of wideband noise-like discontinuous frequency-manipulated signals with continuous phase.

SUBSTANCE: method for transferring wideband noise-like discontinuous frequency-manipulated signals with continuous phase includes generating and transmitting wideband noise-like discontinuous frequency-manipulated signals with continuous phase at transmitting side, while on receiving side doubling of bearing frequencies of received wideband noise-like discontinuous frequency-manipulated signals with continuous phase is performed and spectrum folding and folding in time of symbols of wideband noise-like discontinuous frequency-manipulated signals with continuous phase with doubled bearing frequencies, and during that wideband noise-like discontinuous frequency-manipulated signals with continuous phase are transmitted, each symbol of which is formed of N discontinuous values in form of a combination of alternating pseudo-random series with bearing frequencies of discontinuous values of symbols, nonlinear invariant compression of spectrum of continuous series of information symbols of wideband noise-like discontinuous frequency-manipulated signals with continuous phase is performed for received spectrum of signal with simultaneous generation of signals with doubled bearing frequencies of discontinuous values of symbols and signal of clock frequency of order of discontinuous values of symbol, and folding in time of each symbol of wideband noise-like discontinuous frequency-manipulated signals with continuous phase is performed with doubled bearing frequencies by signals with doubled bearing frequencies of discontinuous values of symbols and by signal of clock frequency of order of discontinuous values of symbols and impulses are formed, appropriate for beginning of each discontinuous value of symbols in given time moment, folding of spectrum of each symbol of wideband noise-like discontinuous frequency-manipulated signals with continuous phase is performed with doubled bearing frequencies by signals with doubled frequencies of discontinuous values of symbols and by generated impulses, appropriate for beginning of each discontinuous value of symbols, and decision is taken about outputting each received symbol of wideband noise-like discontinuous frequency-manipulated signal with continuous phase.

EFFECT: increased trustworthiness of information being transferred, improved resistance to interference due to realization of phase selectivity property, improved concealment and increased resolution.
